Rapid Toolers:

Jordan Medeiros Stephanie Silberstein Hannah Yun

Recap: Our Task

 Utilize 3D CAD software (Solidworks) and 3D printing  Explore modern research fields and apply this technique  Settle on a project idea!

Gantt Chart

Task 1: "Master" SolidWorks

1) Run through tutorials 2) Develop simple models

Task 2: Prototype Design

1) Choose Project 2) Research 3) Develop SolidWorks Model 4) Research Casting Resources 5) Cast

Task 3: Structural Analysis

1) Testing 2) Analysis

Tetrakaidecahedra

 14 faces:  6 squares  8 hexagons  Packs to fill space  Many optimal characteristics, possible application for bone replacement

Original (Ideal) Plan

 Research the ideal metal/material  Construct model as close to scale as possible  Test mechanical properties

J. Biomed Res. Mat. 52, 631-638, 2000

BUT…THERE IS A PROBLEM!

Problems

 Nearly impossible to cast at such a small scale (~ 100 microns)  Impossible to 3DP and cast such intricate structure with a metal

J. Biomed Res. Mat. 52, 631-638, 2000

New Plan

 Theoretical vs actual mechanical properties  Variables:     Strut length Orientation of structure Material composition (if casting is possible) Casting technique  Tetrakaidecahedron vs diamond structure?

Progress…

 Consulted various professionals in the field  Prof. Lorna Gibson  Prof. Sam Allen  3.042 Instructors    Research in pertinent literature Available 3DP facilities?

Solidworks!

Questions to Answer

 Symmetries in the tetrakaidecahedron structure?

  Isotropic/anisotropic properties?

What exactly makes this structure so special?
